I don't believe ABA can cure at all, SAlondon - but it is, by a very long chalk, the quickest way I have seen of getting a kid to his or her full potential. Some other educational methods in this country may not do that at all, imho and ime.
I don't know about the mercury pill mentioned in article - sounds a bit like bunkum to me, but I'm deeply cynical! And how on earth can they say it had an effect, when they were already doing intensive 40 hour a week ABA? Why is everyone so quick to attribute success to the wacky, untested methods, rather than to scientifically-proven methods such as ABA? Pisses me off!
